Heavy rain caused poor drainage flooding and left the region vulnerable to any additional heavy rain as the ground was saturated. Rain began falling during the late evening on the 27th, but fell at its heaviest during the afternoon and evening of the 28th as scattered thunderstorms occurred. The rain ended by late that evening. The evening commute was more difficult as usual as there was much ponding of water in poor drainage locations. Storm totals averaged around two inches.On the 30th, the combination of runoff and melting snow led to isolated low-lying area flooding along the Delaware River in Warren County. In Harmony Township, river flooding reached homes on Riversedge Lane and River Road. The Delaware River at Riegelsville crested at 21.3 feet that morning. Flood stage at that location is 22 feet.Storm totals included 2.65 in Freehold (Monmouth County), 2.58 inches in Sussex (Sussex County), 2.14 inches in Andover (Sussex County), 2.10 inches in Newton (Sussex County), 2.06 inches in Califon (Hunterdon County), 2.04 inches in Belvidere (Warren County), 2.02 inches in Riegelsville (Warren County), 1.95 inches in New Lisbon (Burlington County), 1.88 inches in Bloomsbury (Hunterdon County), 1.75 inches in West Deptford (Gloucester County), 1.74 inches in Mount Laurel (Burlington County), 1.72 inches in Columbia (Warren County), 1.65 inches in Willingboro (Burlington County) and 1.60 inches in Mount Holly (Burlington County). The heavy rain was caused by a low pressure system that formed along the Gulf Coast States. This low pressure system was captured by its support aloft and thus moved only slowly northeast as it tapped abundant moisture from both the Gulf of Mexico and the Atlantic Ocean. The low pressure system moved from western Alabama at 7 a.m. EST on the 27th northeast to eastern Tennessee at 7 p.m. EST on the 27th and eastern Kentucky at 7 a.m. EST on the 28th. A secondary low pressure system formed over North Carolina during the morning of the 28th. It would become the main low pressure system as it moved northeast to near Norfolk, Virginia at 1 p.m. EST on the 28th, Chesapeake Bay at 7 p.m. EST on the 28th, Delaware Bay at 1 a.m. EST on the 29th and about 100 miles east of Atlantic City at 7 a.m. EST on the 29th.
